我使用自动Map器将一个类属性与两个不同的其他类进行Map，如下所示：

var emp = map.Map<EmployeeAddressDto, Employee>(employeeAddressDto);

上面的Map为我提供了如下所示的对象：

Address1 = "some xyz address1"
Address2 = "some xyz address2"
Phone = "0000000000"

然后用EmployeeOtherAddressDtoMap输出对象

map.Map<EmployeeOtherAddressDto, Employee>(emp);

上面的Map将my out更改为：

Address1 = "some other xyz address1"
Address2 = "some other xyz address2"
Phone = null

但我希望它像下面这样：

Address1 = "some other xyz address1"
Address2 = "some other xyz address2"
Phone = "0000000000"

当上面的Map发生时，它使phone不为空，但我希望它保持在以前的Map中定义的状态，尽管我希望覆盖Address1和Address2字段。
以下是我的Map：

CreateMap<EmployeeAddressDto, Employee>()
                .ForMember(dest => dest.Address1, options => options.MapFrom(src => src.Address1))
                .ForMember(dest => dest.Address2, options => options.MapFrom(src => src.Address2))
                .ForMember(dest => dest.Phone, options => options.MapFrom(src => src.Phone))
                .ValidateMemberList(MemberList.None)
                .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null));

CreateMap<EmployeeOtherAddressDto, Employee>()
                .ForMember(dest => dest.Address1, options => options.MapFrom(src => src.Address1))
                .ForMember(dest => dest.Address2, options => options.MapFrom(src => src.Address2))
                .ValidateMemberList(MemberList.None)
                .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null));

我想这样做，在我的Map配置文件，因为我正在使用它在许多地方，不想更新手机没有使用Map器。
